History

Like all Durins after Durin I he was given the name of the first of the Seven Fathers of the Dwarves because he greatly resembled him in both appearance and manner. Indeed it was believed among the Dwarves that he was the reincarnation of Durin I, though whether this is possible is unclear.

Etymology

Durinn is one of the Dwarfs in the Dvergatal. The name means "Sleepy".[1]
